Hi, I've seen a number of shows at Wharton. Without looking at the seating map, my best advice is to sit as close as possible to the center. The rows are long, and not steeply curved, so the ends of the rows are not the best seats. You need to be at least 1/3 of the way in to have a decent view. I would definitely go a few rows further back to be closer to the center. Hope that helps.
